• If you are trying to use Boolean operators, they must be ALL CAPS: (("serie politicas public.") OR ((("etica politica publicas.") OR ("etica politicas publicas."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"serie politicas public.\") or (((\"etica politica publicas.\") OR (\"etica politicas publicas.\"))))~".
• Removing quotes may allow a broader search: (( serie politicas public. ) or ((( etica politica publicas. ) OR ( etica politicas publicas. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("serie politicas public.") or ((("etica politica publicas.") OR ("etica politicas publicas."))))*.
